^ hovering overhead? More like heading up overhead, LOL. Who knew we had Johannes Kepler (Jr.) among our mix?
Jest aside, I love cosmology and my current favorite astrophysicist is Professor Brian Cox. That MoFo has the rare combination of looks and brains plus his mannerism being very engaging as opposed to our own Neil deGrasse Tyson who is an utter hot mess, LOL. Sadly, I am way too dense to understand the math side of things but I love the history of it all.
ETA: have you noticed that some physicists also seem to be very talented musicians? It seems that if you are good at mathematics, you can also understand music but I have never seen it the other way around or else Tommy-Lee, for instance, would've won the Nobel science prize for physics! I wonder if Nathan is good at music? He has the looks for it ;-)
